+===========================
+
+No significant changes since 1.53.0rc1.
+
+
+Synapse 1.53.0rc1 (2022-02-15)
+==============================
+
+Features
+--------
+
+- Add experimental support for sending to-device messages to application services, as specified by [MSC2409](https://github.com/matrix-org/matrix-doc/pull/2409). ([\#11215](https://github.com/matrix-org/synapse/issues/11215), [\#11966](https://github.com/matrix-org/synapse/issues/11966))
+- Add a background database update to purge account data for deactivated users. ([\#11655](https://github.com/matrix-org/synapse/issues/11655))
+- Experimental support for [MSC3666](https://github.com/matrix-org/matrix-doc/pull/3666): including bundled aggregations in server side search results. ([\#11837](https://github.com/matrix-org/synapse/issues/11837))
+- Enable cache time-based expiry by default. The `expiry_time` config flag has been superseded by `expire_caches` and `cache_entry_ttl`. ([\#11849](https://github.com/matrix-org/synapse/issues/11849))
+- Add a callback to allow modules to allow or forbid a 3PID (email address, phone number) from being associated to a local account. ([\#11854](https://github.com/matrix-org/synapse/issues/11854))
+- Stabilize support and remove unstable endpoints for [MSC3231](https://github.com/matrix-org/matrix-doc/pull/3231). Clients must switch to the stable identifier and endpoint. See the [upgrade notes](https://matrix-org.github.io/synapse/develop/upgrade#stablisation-of-msc3231) for more information. ([\#11867](https://github.com/matrix-org/synapse/issues/11867))
+- Allow modules to retrieve the current instance's server name and worker name. ([\#11868](https://github.com/matrix-org/synapse/issues/11868))
+- Use a dedicated configurable rate limiter for 3PID invites. ([\#11892](https://github.com/matrix-org/synapse/issues/11892))
+- Support the stable API endpoint for [MSC3283](https://github.com/matrix-org/matrix-doc/pull/3283): new settings in `/capabilities` endpoint. ([\#11933](https://github.com/matrix-org/synapse/issues/11933), [\#11989](https://github.com/matrix-org/synapse/issues/11989))
+- Support the `dir` parameter on the `/relations` endpoint, per [MSC3715](https://github.com/matrix-org/matrix-doc/pull/3715). ([\#11941](https://github.com/matrix-org/synapse/issues/11941))
+- Experimental implementation of [MSC3706](https://github.com/matrix-org/matrix-doc/pull/3706): extensions to `/send_join` to support reduced response size. ([\#11967](https://github.com/matrix-org/synapse/issues/11967))
+
+
+Bugfixes
+--------
+
+- Fix [MSC2716](https://github.com/matrix-org/matrix-doc/pull/2716) historical messages backfilling in random order on remote homeservers. ([\#11114](https://github.com/matrix-org/synapse/issues/11114))
+- Fix a bug introduced in Synapse 1.51.0 where incoming federation transactions containing at least one EDU would be dropped if debug logging was enabled for `synapse.8631_debug`. ([\#11890](https://github.com/matrix-org/synapse/issues/11890))
+- Fix a long-standing bug where some unknown endpoints would return HTML error pages instead of JSON `M_UNRECOGNIZED` errors. ([\#11930](https://github.com/matrix-org/synapse/issues/11930))
+- Implement an allow list of content types for which we will attempt to preview a URL. This prevents Synapse from making useless longer-lived connections to streaming media servers. ([\#11936](https://github.com/matrix-org/synapse/issues/11936))
+- Fix a long-standing bug where pagination tokens from `/sync` and `/messages` could not be provided to the `/relations` API. ([\#11952](https://github.com/matrix-org/synapse/issues/11952))
+- Require that modules register their callbacks using keyword arguments. ([\#11975](https://github.com/matrix-org/synapse/issues/11975))
+- Fix a long-standing bug where `M_WRONG_ROOM_KEYS_VERSION` errors would not include the specced `current_version` field. ([\#11988](https://github.com/matrix-org/synapse/issues/11988))
+
+
+Improved Documentation
+----------------------
+
+- Fix typo in User Admin API: unpind -> unbind. ([\#11859](https://github.com/matrix-org/synapse/issues/11859))
+- Document images returned by the User List Media Admin API can include those generated by URL previews. ([\#11862](https://github.com/matrix-org/synapse/issues/11862))
+- Remove outdated MSC1711 FAQ document. ([\#11907](https://github.com/matrix-org/synapse/issues/11907))
+- Correct the structured logging configuration example. Contributed by Brad Jones. ([\#11946](https://github.com/matrix-org/synapse/issues/11946))

+
+
+Deprecations and Removals
+-------------------------
+
+- Drop support for `webclient` listeners and configuring `web_client_location` to a non-HTTP(S) URL. Deprecated configurations are a configuration error. ([\#11895](https://github.com/matrix-org/synapse/issues/11895))
+- Remove deprecated `user_may_create_room_with_invites` spam checker callback. See the [upgrade notes](https://matrix-org.github.io/synapse/latest/upgrade.html#removal-of-user_may_create_room_with_invites) for more information. ([\#11950](https://github.com/matrix-org/synapse/issues/11950))
